船载三轴天线极化稳定技术研究
|
摘要
为解决船载卫通天线跟踪线极化卫星时,船摇对天线极化的扰动问题,提出了一种船载三轴天线极化稳定方法。通过坐标旋转推导出包含船体姿态角、天线对星地理角的三轴天线目标极化角计算公式,在船摇状态下,实测极化角与实时计算的目标极化角保持一致,从而实现极化稳定。该方法已经应用在一个大型船载卫通天线,实践表明,穿越赤道时的高仰角跟踪情况得到了明显改善。
In order to avoid the disturbance to antenna polarization caused by ship-swing when a shipborne satellite communication antenna is a tracking linear polarized satellite,a polarization stabilization method of shipborne triaxial antenna is proposed in this paper.The matrix formula of polarization angle of triaxial antenna is deduced,which includes the attitude angles of ship-hull and the angle of direction to satellite,and the antenna keeps the measured polarization angle equal to the target polarization angle calculated in real time,so as to stabilize the antenna polarization. The method has been applied to a large shipborne satellite communication antenna. The practice shows that the high elevation tracking across the equator is improved significantly.
